Reasons can be various.
There are typical behavior problems stemming from passive parenting or lack of discipline and structure, but she seems awefully young for that. Any one of these issues could be explored:
*B6 deficiency will cause agression. Consider a B-complex liquid, which could help her nervous system. I recommend trying this. Keep carbs and sugars to a minimum as they destroy B stores as well. I would add a probiotic, like accidophilus or lactobaccilus, which will feed some b vits and help combat bacteria.
* lead poisoning. (keep in mind some shots can have lead in them. Children who have compromised immune systems seem to be affected by vaccinations moreso than healthy children.
* Acid base imbalance (acidosis or alkalosis) which can include low vit d, diabetic acidosis (or phosphorus imbalance by using laxatives)
* Hypoglycemia
* Hypoglycemic attack
* Thyroid imbalance
* autism
* Soto/Reyes syndrome
* Nyssen Van Bogaert syndrome
* Omega 3 imbalance (Cod liver oil will provide omega 3 and also good vit d and A source)Walmart has an orange flavored one.
* bacterial infections, which can cause encephalitis, like west nile virus, HSV, lyme disease, or encephalitis caused by parasites or immunizations.
* brain tumors
* water on the brain/pressure
* past head trauma or birth canal trauma (I've seen dogs which had head trauma as puppies snap and have unprovoked agression.You might check with an accupuncture/chiropractic specialist to help with this)
* partial seizures in the hypothalamus or lymbic system
would show:
sudden unprovoked aggression, mood changes before the seizure, dialated pupils,...after the agression the person may be depressed,lethargic,unresponsive, staring at walls, or sleepiness.
Take note of any confusion, motor changes in posture, headache, nausea, tachardia, restlessness or motor coordination issues before an agression attack.
* Yeast doctors claim that yeast overgrowth causes agression with head banging in very young children.Look up candida infection online.
(babies can be born with fungal infections inside ..presenting as thrush and fungal diaper rashes. Genitian violet, nystatin, grapeseed extract, caprylic acid, and oregano oil drops under the tounge all help combat fungus, and should be safe with your toddler, if need be.
